Abstract
This invention generally relates to products and processes used to determine the presence of bacteria in a sample and particularly relates to a culture medium which may be used in products and processes to allow early detection and count of coliform bacteria. The bacterial culture medium which facilitates the early detection and count of coliform bacteria is a mixture of tryptose, lactose, sodium chloride, bile salts, guar gum and an excess amount of phenol red sufficient to provide a high concentration of phenol red in close proximity to the growing bacteria in order to allow detection and count of the growing bacteria in less than 12 hours.
